My Brother HL-20 laser printer makes repeated identical smudges on one side of the paper. Running MANY copies through it did not clear this problem. How can I clean / remove this problem?

All laser printers have 2 cylinders in the image..the mag roller, and the drum.
Usually the drum is marked by a foreign object  e.g label or someone has touched it with their finger.
If you replace the cartridge your problem should go away

The ink smudges on the paper.

The "fuser" is the part of the laser-printer that melts the dry toner-ink onto the paper.
If the fuser is not getting hot enough, or is not working at all, then the toner-ink will smudge.

Take the printer to a qualified technician for servicing.

Have black smudge line in middle of paper have new toner and drum

Try taking out your toners, and on the drum you will see a green button which you can slide from side to side (it's on each of the colored slots). Make sure you put the the white plastic cover up and then it will slide. I hope this will help you.

Toner smudges along the extreme right side of the paper

If the smudges are gradually fading then it's likely just excess toner hitting the fuse drum. Try a few cleaning cycles/test prints and see if that makes it go away. If not, see if you can get a replacement toner.
